Also, once you are working in R, you need to familiarize yourself with the concept of a factor object. These are used to represent categories in R. Unlike SAS, R considers the categorical/quantitative distinction as part of the variable, e.g. in modeling you don't use CLASS directives, you ensure that the variable is a factor. You create factors from numerical codes with factor(), and in the process you may attach meaningful labels to the factor levels.
